Assessment of fundamental strategic issues in structural change in United Kingdom and South African ports by systemic scenarios

The future complexity of strategic issues in international structural change was demonstrated by UK and SA ports. This arose from the likely extent of structural constraints and the effects of stakeholder power. From a review of emerging Advanced Systems Theory a new Boundary -spanning perspective of strategy was developed, that led to the specification of conceptual circumstances of potential outcomes of change. Since existing systems methodologies could not accommodate future power relationships, a new methodology and data collection technique was developed. The circumstances were developed into multiple scenarios which were judged by international decision-makers. These judgements were subjected to quantitative and qualitative analysis from a Strategic Choice Perspective. The outcome was a Boundary -spanning 'Long-term Strategic Service Industry' model which proposed the outlines of the future strategy and organisational structure that ought to be adopted to meet 'public interest' constraints. A dual subject and methodological contribution was made

3D-in-2D Displays for ATC.

This paper reports on the efforts and accomplishments of the 3D-in-2D Displays for ATC project at the end of Year 1. We describe the invention of 10 novel 3D/2D visualisations that were mostly implemented in the Augmented Reality ARToolkit. These prototype implementations of visualisation and interaction elements can be viewed on the accompanying video. We have identified six candidate design concepts which we will further research and develop. These designs correspond with the early feasibility studies stage of maturity as defined by the NASA Technology Readiness Level framework. We developed the Combination Display Framework from a review of the literature, and used it for analysing display designs in terms of display technique used and how they are combined. The insights we gained from this framework then guided our inventions and the human-centered innovation process we use to iteratively invent. Our designs are based on an understanding of user work practices. We also developed a simple ATC simulator that we used for rapid experimentation and evaluation of design ideas. We expect that if this project continues, the effort in Year 2 and 3 will be focus on maturing the concepts and employment in a operational laboratory settings

5th International Conference on Advanced Research Methods and Analytics (CARMA 2023)

Research methods in economics and social sciences are evolving with the increasing availability of Internet and Big Data sources of information. As these sources, methods, and applications become more interdisciplinary, the 5th International Conference on Advanced Research Methods and Analytics (CARMA) is a forum for researchers and practitioners to exchange ideas and advances on how emerging research methods and sources are applied to different fields of social sciences as well as to discuss current and future challenges.Martínez Torres, MDR.; Toral Marín, S.

Risk Assessment in Air Traffic Management

One of the most complex challenges for the future of aviation is to ensure a safe integration of the expected air traffic demand. Air traffic is expected to almost double its current value in 20 years, which cannot be managed without the development and implementation of a safe air traffic management (ATM) system. In ATM, risk assessment is a crucial cornerstone to validate the operation of air traffic flows, airport processes, or navigation accuracy. This book tries to be a focal point and motivate further research by encompassing crosswise and widespread knowledge about this critical and exciting issue by bringing to light the different purposes and methods developed for risk assessment in ATM

Combining SOA and BPM Technologies for Cross-System Process Automation

This paper summarizes the results of an industry case study that introduced a cross-system business process automation solution based on a combination of SOA and BPM standard technologies (i.e., BPMN, BPEL, WSDL). Besides discussing major weaknesses of the existing, custom-built, solution and comparing them against experiences with the developed prototype, the paper presents a course of action for transforming the current solution into the proposed solution. This includes a general approach, consisting of four distinct steps, as well as specific action items that are to be performed for every step. The discussion also covers language and tool support and challenges arising from the transformation

Development of a System for the Training Assessment and Mental Workload Evaluation

Several studies have demonstrated that the main cause of accidents are due to Human Factor (HF) failures. Humans are the least and last controllable factor in the activity workflows, and the availability of tools able to provide objective information about the user’s cognitive state should be very helpful in maintain proper levels of safety. To overcome these issues, the objectives of the PhD covered three topics. The first phase was focused on the study of machine-learning techniques to evaluate the user’s mental workload during the execution of a task. In particular, the methodology was developed to address two important limitations: i) over-time reliability (no recalibration of the algorithm); ii) automatic brain features selection to avoid both the underfitting and overfitting problems. The second phase was dedicated to the study of the training assessment. In fact, the standard training evaluation methods do not provide any objective information about the amount of brain activation\resources required by the user, neither during the execution of the task, nor across the training sessions. Therefore, the aim of this phase was to define a neurophysiological methodology able to address such limitation. The third phase of the PhD consisted in overcoming the lack of neurophysiological studies regarding the evaluation of the cognitive control behaviour under which the user performs a task. The model introduced by Rasmussen was selected to seek neurometrics to characterize the skill, rule and knowledge behaviours by means of the user’s brain activity. The experiments were initially ran in controlled environments, whilst the final tests were carried out in realistic environments. The results demonstrated the validity of the developed algorithm and methodologies (2 patents pending) in solving the issues quoted initially. In addition, such results brought to the submission of a H2020-SMEINST project, for the realization of a device based on such results

SIMULATING SEISMIC WAVE PROPAGATION IN TWO-DIMENSIONAL MEDIA USING DISCONTINUOUS SPECTRAL ELEMENT METHODS

We introduce a discontinuous spectral element method for simulating seismic wave in 2- dimensional elastic media. The methods combine the flexibility of a discontinuous finite element method with the accuracy of a spectral method. The elastodynamic equations are discretized using high-degree of Lagrange interpolants and integration over an element is accomplished based upon the Gauss-Lobatto-Legendre integration rule. This combination of discretization and integration results in a diagonal mass matrix and the use of discontinuous finite element method makes the calculation can be done locally in each element. Thus, the algorithm is simplified drastically. We validated the results of one-dimensional problem by comparing them with finite-difference time-domain method and exact solution. The comparisons show excellent agreement

Metropolitan Research: Methods and Approaches

Metropolitan research requires multidisciplinary perspectives in order to do justice to the complexities of metropolitan regions. This volume provides a scholarly and accessible overview of key methods and approaches in metropolitan research from a uniquely broad range of disciplines including architectural history, art history, heritage conservation, literary and cultural studies, spatial planning and planning theory, geoinformatics, urban sociology, economic geography, operations research, technology studies, transport planning, aquatic ecosystems research and urban epidemiology. It is this scope of disciplinary - and increasingly also interdisciplinary - approaches that allows metropolitan research to address recent societal challenges of urban life, such as mobility, health, diversity or sustainability
